17, and each of the crescent-shaped members 15 and 16 are provided with the curved portions 18, as illustrated. The curved portions 18 are so spaced apart and so shaped that they form the approximately. circular opening 19 at the center of the circular space occupied by the crescent members 15 and 16, and they also form the open curved slots 20, all as will be clear from Fig. 5. At a distance from the extreme end members 15 and 16, the main body portion 11 is bent or dished as indicated at 21 and 22, and the dished portion is provided with the semicircular extension 23, as shown. Pivotally mounted on each side of this dished extension are the wire tensioning disks 24 and 25, as will be clear from Figs. 2 and 3. The tensioning disks24 and 25 are provided with the radial slots 26 adapted to receive the ends of the 'wire, and one of said disks, as 25, for ex ample, is provided with ratchet teeth '27 on 'its periphery engaged by a pawl 28 controlled by a spring 29. 30 represents an operating handle to which said pawl is pivoted, as at 31, and said disks 24 and 25, as well as said handle 30, are secured to the main body portion 11 or to the extension 23 thereof by means of the common pivoting pin or short axle 33, as shown.

On the strip-like member 13 is rigidly secured the U-shaped member 34 which straddles said member 13, as best shown in Fig. 5, and opposite said member 34 is the U- shapecl member 35 rigidly secured to the strip-like member 14. To the rear of the slot 12 there is also secured to the main body portion 11 a U-shaped guide member having the parts 37 and 38located on opposite sides of said main body portion 11, as will be clear from Figs. 3 and 4. Said members 37 and 38 are so spaced from the U-shaped member 35 as to form a slot or guideway for the cutter members 39 and 40, with which the too-l is provided. Said cutter members are preferably two in number, as illustrated, and are pivoted as at 41 to the extreme end members 37 and 38, as at 44. Said cutter lever 43 is bent as at 46 in a direction away from the main body portion 11 in order that it may pass the dished portion 21, 22 of said main body portion, and it is again bent inan opposite direction as at 47, seeFig. 2, in

order that its handle 48 may lie comparatively close to the handleportion 49 of said main body portion 11.

50 represents a retainer latch secured to the main body portion 11, as at 51, which extends outwardly and downwardly from said main body portion and terminates in a hook 54, see Fig. 3. Thusit will be seen that-the latch member 50 not only serves as a guide to prevent the lever 43 from be ing'bent inwardly so as to interfere with the operation thereof, but the hooked end 54 of the latch is adapted to receive and retain the member 43 in a position close to the main handle portion 49 so that the opening between the cutter 40 and its companion member will permit the wire 8 to be threaded through the end of the device into the tensioning drum 25. In other words, theweight of the cutter actuating lever 43 would have a tendency to move the cutters 39 and 40 to such a position as to obstruct said open in'g unless said latch'or' hook 54 were employed. The extreme end of the main body portion 11 is provided with a pin 52 on which is swiveled the bearing member 53 so that the latter may turn independently of the said also engaged by a dog 56 controlled by a spring 57, which dog is pivoted as at 58 to a plate-like member 59 secured to the ex tension 23 of the dished portion 21, 22 of the main body portion 11, as best shown in Figs. 3 and 4. The cutters 39 and 40 may be integrally or rigidly joined together asby means of the web member 60, see Figs. 3 and 6, so as to insure their rigidity and proper cutting action. The extreme end 42 of the cutting lever 43 is curved as at 61, so that when said lever is turned through a predetermined arc, said curved portion will strike the surface 62, separating the two forked portions of the member 35, and thus limit the movement of the cutters 39 and 40. all as will be clear from Fig. 3.

The operation of this tool is as follows: A loop of wire, such as 7, having been placed as indicated in Fig. 1 or around a plurality of any members that are to be readily and firmly joined together, the extreme end portions 8 and 9 of said wire are introduced through the slots 20 between the crescent-shaped members 15 and 16, and are led to the disks 24 and 25,- where the said wire ends 8 and 9 are passed through the slots 26 in said disk members and their ends bent around the peripheries of said disks 24 and 25, all as will be clear from Figs. 2, 3 and 4. After the wires have been thus secured'to the disks 24 and 25, a few motions may be had with the lever '30 in order to rotate said disks 24.and 25 with the aid of the pawl 28011 the said lever 30, whereupon the slack of said wires will be taken up, and the crescent-shaped disks 15 and 16 brought in close proximity to the surface .of the parts to be held together. When in this condition, the wires will be found to'pass throughthe central circular opening 19 between the curved portions 18 of the crescent-shaped disk 15, and then the handle 30 may be operated until the desired ingle'ver 30 in the other hand, and, rotates an" lever ate-ta in are" of as main" turning said lever about its pivot 44 and ill) ' turning of said body portionso as to twist actuating the cutters 39- and 40 to sever the twisted wire against the edge of the U-shaped member 34, .all as will be clear from Figs. 2, 3 and 8. V g

'It will be observed that the ends of the wire are disposed alongside of each other,

i and both extend into the opening in the end of the tool in the same direction. it

vwill also be seen that these two free ends oat" the wire are spirally twisted together, and, that after being spirally twisted together,-' both terminal ends are severed by the cut ters- It will also'be seen that the extent or length of'the spirally twisted portion is limited by the length of the slot 12. That is to say, the number of twists imparted to the wire ends in twisting themtogether is limited to the length of the slot 12, within which the twists are formed. This is an important feature of the tool, as thereby the danger of over-twisting, and hence of thereby breakingthe wire, is avoided.

What is claimed is V 1. In a wire tensioning and twisting tool, the combination of an elongated main body portion, means at one end of the main body portion for receiving the free ends of a wire to; be joined together, with said endsfdisposed, side by side and extending in the same direction, means for tensioning said Wires, means at the other end of said body portion to facilitate the turning of said body portion so as to twist together and tension said wires,and a cutter to sever said wires.

2.
